Available in PDF, EPUB and Kindle. Book excerpt: Over the past few years, the technology and performance of Automated Speech Recognition (ASR) systems has been improving steadily. This has resulted in their successful use in a number of industrial applications. Motivated by this success, a look was taken at the application of ASR to Air Traffic Control, a task whose primary means of communication is verbal. In particular, ASR, and audio playback was incorporated into an Air Traffic Control Simulation task in order to replace blip-drivers, people responsible for manually keying in verbal commands and simulating pilot responses. This was done through the use of a VOTAN VPC2000 ASR continuous speech recognition system which also possessed a digital recording capability. Parsing systems were designed that utilized the syntax of ATC commands, as defined in the controller's handbook, in order to detect and correct recognition errors. As well, techniques whereby the user could correct any recognition errors himself were included. Finally, some desirable features of ASR systems to be used in this environment were formulated based on the experience gained in the ATC simulation task and parser design. These predominantly include continuous speech recognition, a simple training procedure, and an open architecture to allow for the customization of the speech recognition to the particular task at hand required by the parser.
Download or read book Automatic Speech Recognition and Understanding in Air Traffic Management written by Hartmut Helmke and published by . This book was released on 2024-03-08 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Automatic Speech Recognition and Understanding (ASRU) has the potential to reduce air traffic controllers' (ATCos) workload and to enhance air traffic management (ATM) safety. Automatic Speech Recognition (ASR) transforms voice signals into a sequence of words, e.g., "speed bird four one six descend flight level one two zero". Automatic Speech Understanding extracts the meaning from this word sequence, e.g., that the aircraft with the callsign "BAW416" should "DESCEND" to roughly "twelve thousand feet". The Special Issue contains 12 articles authored by 54 different authors, working for 23 institutions that are located in 13 countries on four continents. These articles discuss (a) ontologies for modeling words and semantics, (b) the extraction of aircraft callsigns and complex commands, (c) ASRU support for ATCos through callsign highlighting, the filling of aircraft radar labels and flight strips for approach, tower, and apron environments, (d) supporting simulation pilots, (e) speech activity detection, speaker role classification, natural language processing, English language identification, (f) combining ASRU with surveillance data, (g) joining speech and gaze data, and (h) a safety assessment.
Download or read book The Integration of Automatic Speech Recognition Into the Air Traffic Control System written by Joakim Karlsson and published by . This book was released on 1990 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today, the Air Traffic Control (ATC) system relies primarily on verbal communication between the air traffic controllers and the pilots of the aircraft in the controlled airspace. Although a computer system exists that processes primary radar, secondary radar, and flight plan information, the information contained within the verbal communications is not retained. The introduction of Automatic Speech Recognition (ASR) technology would allow this information to be captured for processing. The research presented in this paper examines the feasibility of using ASR technology in the Air Traffic Control environment. The current status of the technology is assessed. Problems that are unique to ATC applications of voice input are identified. Since ASR technology is inherently a part of the man-machine interface between the user and the system, emphasis is placed on the relevant human factors issues. A man-machine model is presented which demonstrates the use of mixed input modalities, automatic error detection and correction techniques, and the optimal use of feedback to the controller. Much of the potential benefit of introducing ASR technology into the Air Traffic Control system is a result of the highly constrained language used by air traffic controllers. Consequently, the information content of the ATC language must be determined, and methods must be designed to process the various levels of knowledge inherently available in ATC communications. The man machine model adopted in this paper demonstrates techniques to utilize syntactic, semantic, and pragmatic information to improve overall recognition accuracy. An intelligent, adaptive voice input parser is presented.

Download or read book Voice Recognition and Artificial Intelligence in an Air Traffic Control Environment written by Robert Francis Hall and published by . This book was released on 1988 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid growth of air carrier, general aviation, and military traffic has strained this nation's Air Traffic Control (ATC) system. The symptoms of this strain appear as controller fatigue, low controller moral, and the occasional creation of a hazardous situation caused by human error. The current method employed to improve the ATC system has been in the form of increasing its air traffic handling capacity by adding more machinery and manpower. Thus, machines with greater processing power and more humans are coupled into a man machine system which is destined to continually grow. Little has been done in finding new forms of technology to increase the joint efficiency of man and machine. Two relatively new technologies which could create a path towards greater system efficiency are the technologies of voice recognition and artificial intelligence. With greater system efficiency, less controller fatigue and better air safety are expected. Where to apply these technologies, in what form, and how deep these technologies can be integrated into the ATC system are questions which deserve inquiry. This research details a method to answer these questions, develops prototype equipment from which to experiment, and establishes a basis from which other research efforts may be launched. A review of literature indicates that current efforts at applying voice recognition in flight operations are centered around pilot task improvement and special projects such as the space shuttle. While these efforts are certainly important, the controller environment can be just as demanding, stressful, and important. It is within this light that this study is launched.

Download or read book Fatal Words written by Steven Cushing and published by University of Chicago Press. This book was released on 1994-03-04 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: On March 27, 1977, 583 people died when KLM and Pan Am 747s collided on a crowded, foggy runway in Tenerife, the Canary Islands. The cause, a miscommunication between the pilot and the air traffic controller. The pilot radioed, "We are now at takeoff," meaning that the plane was lifting off, but the tower controller misunderstood and thought the plane was waiting on the runway. In Fatal Words, Steven Cushing explains how miscommunication has led to dozens of aircraft disasters, and he proposes innovative solutions for preventing them. He examines ambiguities in language when aviation jargon and colloquial English are mixed, when a word is used that has different meanings, and when different words are used that sound alike. To remedy these problems, Cushing proposes a visual communication system and a computerized voice mechanism to help clear up confusing language. Fatal Words is an accessible explanation of some of the most notorious aircraft tragedies of our time, and it will appeal to scholars in communications, linguistics, and cognitive science, to aviation experts, and to general readers.

Download or read book The Art and Business of Speech Recognition written by Blade Kotelly and published by Addison-Wesley Professional. This book was released on 2003 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most people have experienced an automated speech-recognition system when calling a company. Instead of prompting callers to choose an option by entering numbers, the system asks questions and understands spoken responses. With a more advanced application, callers may feel as if they're having a conversation with another person. Not only will the system respond intelligently, its voice even has personality. The Art and Business of Speech Recognition examines both the rapid emergence and broad potential of speech-recognition applications. By explaining the nature, design, development, and use of such applications, this book addresses two particular needs: Business managers must understand the competitive advantage that speech-recognition applications provide: a more effective way to engage, serve, and retain customers over the phone. Application designers must know how to meet their most critical business goal: a satisfying customer experience. Author Blade Kotelly illuminates these needs from the perspective of an experienced, business-focused practitioner. Among the diverse applications he's worked on, perhaps his most influential design is the flight-information system developed for United Airlines, about which Julie Vallone wrote in Investor's Business Daily "By the end of the conversation, you might want to take the voice to dinner." If dinner is the analogy, this concise book is an ideal first course. Managers will learn the potential of speech-recognition applications to reduce costs, increase customer satisfaction, enhance the company brand, and even grow revenues. Designers, especially those just beginning to work in the voice domain, will learn user-interface design principles and techniques needed to develop and deploy successful applications. The examples in the book are real, the writing is accessible and lucid, and the solutions presented are attainable today. 0321154924B12242002
